satcat5::irq::VirtualTimer Class Reference

Detailed Description

Poll any OnDemand object using a TimeRef.

SatCat5 event-loop concepts.

This class polls the system time (SATCAT5_CLOCK) and calls request_poll() at the designated interval. On platforms that do not have easy access to hardware interrupts, this is the preferred method of polling the global timekeeper.
